The short version
Cryptocurrency is a digital asset. Ownership is recorded on a shared ledger that many computers keep copies of, instead of on one bank’s private database. Bitcoin is the first widely used example. Thousands of other tokens exist. Most of them are experiments. Some are scams. A ticker and a price do not make something safe.
People use the word “crypto” for the assets, the networks, and sometimes the whole industry. On BitBuddy we use it more narrowly: a unit you can study, and — if you want — paper-trade, without treating a quote as a promise.
How this differs from a bank balance
A checking account is a claim on a regulated institution. The bank can freeze a login, reverse a wire in some cases, and reset a password. Crypto networks generally do not work that way. If you control the keys, you can sign a transfer. If you lose the keys, the network has no help desk that can restore them. If you send to the wrong address, there is usually no chargeback.
That tradeoff is the whole subject. Some people want fewer intermediaries. Some people want the protections of a bank or a licensed exchange. Both instincts are reasonable. This classroom does not tell you which to pick.
- Ledger, not an IOU from BitBuddy. On a public chain, the record is the asset.
- Rules in software. Issuance and transfer rules are written in the protocol. They can still change if enough of the network agrees — “code is law” is a slogan, not a guarantee.
- Price is a market, not a fact of nature. Quotes move. They can go to zero.
Coins, tokens, and why the list is long
Bitcoin is a network with its own ledger and a native unit (BTC). Ethereum is another network; many tokens live on it as entries in smart contracts. Other chains copy pieces of both ideas. BitBuddy’s paper wallet shows a cached live quote for BTC and ETH, plus labeled sim coins (BUDDY, PUP, NUG) and classroom-market fakes (ATUSD, VOLT, MESA). Those fakes bounce on a timer. They are not markets.
A long list of tickers is not a reason to buy any of them. Treat an unfamiliar name as unknown until you can explain, in your own words, what the network actually does.
What a “price” is doing on this site
When we show a Bitcoin price, it is a cached quote from a market-data provider — useful for the lesson, not a live order book, and not an offer to buy or sell. Simulated lesson coins do not have an outside market at all. Nothing here is a brokerage quote you can hit.
BitBuddy is a paper classroom. Balances have no cash value. Nothing on this site is financial, investment, or tax advice. Do your own research if you later look at a real venue.
Risk, said plainly
Crypto assets are volatile. They can be lost to phishing, malware, or a forgotten seed. Exchanges can halt withdrawals. Law and tax treatment depend on where you live. None of that is solved by a friendly tutorial.
The honest use of a site like this is to learn the vocabulary — wallet, fee, confirmation, spread — while the money is imaginary. The scams lesson covers the cons that show up before anyone is ready for a real account.
A note on language
“Coin,” “token,” “asset,” and “crypto” get used interchangeably in headlines. On this site, paper unit means a classroom balance. Live quote means a cached market number for teaching. Sim means we invented the ticker. If a word feels slippery, prefer the labeled term on the dashboard over a social post.
What to do next
Next we look at wallets and keys: what actually controls a balance, and why a seed phrase is not something you type into a website. After that, Bitcoin, transactions, the chain, and the mining game. In a hurry? The 10-minute path jumps to wallets, then the sandbox, then a paper trade.
